How would you expect the following series of compounds to compare in behavior in the two tests(SN1 vs. SN2)?

Question

CH3CH=CHCH2Br (1-bromo-2-butene)

CH3-C=CHCH3 
    l
    Br

CH3CH2CH2Br (1-bromopropane)

I know primary alkyl halides like 1-bromopropane favor SN2 reactions and tertiary alkyl halides favor SN1 reactions. But I don't get what this question is asking.

I can't help answer the question but I can tell you what it is asking. The question wants you to RANK the compounds top to bottom in SN1 or SN2 (or at least indicate which is more likely to occur as SN1 or SN2.
